Abstract: In a digital video signal recording/reproducing apparatus suited to recording of digital VTR video and audio signals by using a rotary cylinder, as for the video signal with frame frequency fN of 30 Hz or 29.97 Hz, the rotating frequency of the cylinder is set to 2.5 times fN. On the other hand, as for the signal with frame frequency fP of 25 Hz, the rotating frequency of the cylinder is set to 3.0 times fP.

Abstract: A process for the preparation of drugs for the treatment of hepatitis B, characterized by the identification of transferrin receptor CD71 as a membrane structure responsible for the HBV infection. The drugs according to the invention for the treatment of hepatitis B can be characterized by the fact of comprising as active agent the soluble transferrin receptor bound to a toxin, for example the tetanus toxin. The invention relates also to drugs for the treatment of hepatitis B, characterized by the fact of comprising as active agent peptides homologous to amino acid sequence of HBsAg envelope protein of HBV. Hence, these peptides act as competitors with the virus for the entry into the cells through transferrin receptor CD71.

Abstract: A battery charging circuit is provided with a thermal cut-out (TSI) whose normally closed contacts are in series with the main terminals of a thyristor (SCR1). The thyristor is switched ON on commencement of battery charging by the charging of a capacitor C1 (which remains charged even when the contacts of cut-out TS1 open as a result of the battery temperature rising on completion of charging). Consequently thyristor SCR1 remains latched OFF even if the contact of cut-out TS1 close, and can only be turned ON again by disconnecting battery B1, which enables capacitor C1 to discharge via a diode CR1.

Abstract: A detector for detecting z-axis position in the plane of the fan beam of a computed tomography machine with respect to the detector array employs a pair of slotted masks over independent detector cells, the slots creating exposed widths that decrease and increase along their length. The intensity signals from the two detector cells so masked are subtracted to produce a z-axis position signal eliminating the effect of dark currents. Multiple cells may be ganged to reduce the eflects of sensitivity variations among pairs of detector cells. The z-axis position signal may be used to control the z-axis position of the fan beam with respect to the detector array and to reduce the effect of the detector cell's variation in sensitivity.

Abstract: In a developing apparatus wherein two-component developer consisting of toner (T) and carrier (C) is used and the rotation number of a developing roller (22) selected under normal mode can be changed under another mode under which the amount of toner used is different from that under normal mode, a magnetic sensor (30) is used as means for detecting toner concentration in a developer (D) containing section. Input voltage applied to the magnetic sensor (30) is adjusted and determined in such a way that the output voltage of the magnetic sensor (30) which is previously set relative to a reference toner concentration in the developer (D) becomes equal to a reference voltage, on which it is determined whether the adding of toner is started or stopped, even though the rotation number of the developing roller (22) selected under one mode is changed under another mode. The output voltage of the magnetic sensor (30) rises as the toner concentration in the developer (D) becomes low. The reference voltage is set 4V relative to the reference toner concentration of 4%, for example, and when the output voltage becomes larger than the reference voltage, the adding of toner is started. The output voltage becomes lower as the toner concentration becomes higher and when the output voltage becomes smaller than the reference voltage or equal to it, the adding of toner (T) is stopped. When the rotation number of the developing roller (22) is changed in this manner to change one mode to another, such input voltage that corresponds to the rotation number of the developing roller (22) is applied to the magnetic sensor (30) to control the toner density in the developer (D) by comparing the output voltage of the magnetic sensor (30) with the reference voltage selected under this another mode.

Abstract: A thermal-dye-bleach construction comprising a thermal nucleophile-generating agent in association with a styryl dye having a nucleus of general formula (I):
       
representing the nucleus of a styryl dye in which
     R = methyl or ethyl group   Y = alkoxy of 1 to 20 carbon atoms   m = 1 or 2,   n = 1, 2, or 3, and   x e  = an anion   
     The aromatic fused benzene portion of the indolenine ring may be further substituted with commonly acceptable dye substituents such as alkyl and substituted alkyl (of 1 to 10 carbon atoms) groups, alkoxy groups (preferably of 1 to 10 carbon atoms), fused aromatic rings (as to make the benzene ring a fused naphthalene ring), halogen (including fluoro), cyano, nitro, carboxamido, amido, etc. One or two substituents chosen variously from said group may also be present on the phenyl ring to which the alkoxy group is attached. These substituents and their combinations should not be chosen so as to alter the absorption characteristics of the dye greatly enough to remove the maximum absorption from between 300 and 490 nm. 
     X e  may be any anion, but certain classes of anions and certain particular anions are preferred. Aromatic and perfluorinated anions and, in particular dodecylbenzenesulfonate and especially perfluoro(ethylcyclohexane sulfonate) are preferred on account of their solubilizing power, but simpler anions such as iodide, chloride, bromide, methylsulfate, perchlorate and the like may also be used.

Abstract: A structure and method for forming contact vias in integrated circuits. An interconnect layer (20) is formed on an underlying layer (22) in an integrated circuit. A buffer region (26) is then formed adjacent to the interconnect layer, followed by forming an insulating layer (28) over the integrated circuit. Preferably, the insulating layer (28) is made of a material which is selectively etchable over the material in the buffer region (26). A contact via (30) is then formed through the insulating layer (28) to expose a portion of the interconnect layer (20). During formation of the contact via, the buffer region (26) acts as an etch stop and protects the underlying layer (22). The buffer region (26) also ensures a reliable contact will be made in the event of an error in contact via placement.
